Question

total number of electrons in 1 molecule of CO2​

Answer 1

Answer:

22

Explanation:

electron present in 1 carbon atom is +2

electron present in one oxygen atom is=6+2×8=

22

Answer 2

Answer:

22

Explanation:

in 1 molecule

there is 1 carbon atom with no charge

so number of protons( atomic number) = number of electrons = 6

there is 2 atoms of oxygen with null charge

so number of protons( atomic number) = number of electrons

but there are two atoms so 2 x atomic number = 2 x 8 = 16

so total number of electrons in CO2 is 6 + 16 = 22
